SPEECH COMPRESSION TECHNIQUES: A REVIEW
Creators
Description
Speech is the vocalizer form of human communication,and based upon the syntactic combination of lexical and vocabularies. The aim of speech coding is to compress the speech signal to the highest possible compression ratio bu t maintaining user acceptability.There are many methods for speech compression like Linear Pre dictive coding (LPC),Code Excited Linear Predictive coding (CELP),Sub-band coding,T ransform coding:- Fast Fourier Transform (FFT),Discrete Cosine Transform (DCT),Continuous Wavelet Transform (CWT),Discrete Wavelet Transform (DWT),Variance Fractal Compression (VFC),Discrete Cosine Transform (DCT),Psychoacoustics and etc. Few of them are discus in this paper.
